earner Thisinvention relates to a machine for hulling oatsor. similar grain and which can "6 Oats arenow usedlargel It is an object of this:invention,-therefore, 15 to provide a very simple and eflicient hulling c or comminuting apparatuscomprising-a 'rotary' member-"having ribs at either side thereof which receives and distributes the material. i a

i It is a further "object of the invention .to

rovide. a simple and eflicient machine for liulling or operating upon a stock 'feed comprising a casing, a disk disposed'thereinhav- ,ing blades or flutesat either side for disa tributing 'the material, a ring extending about saiddisk against whic'h the material is rojected, and an outlet conduit! leading groin said casing, said ring extending across the opening into said outletconduit.

' It Is a' further, ob'ect of the invention to provide'a'machine or hulling 'or otherwise 5 operating onstock' feed materlal comprising a casing'having substantially vertical sides, afshaft extending .therethrough, a disk icarriedon said shaft between said sides,-

havingvblades for flutes thereon, an annular disk overlyingsaid flutes, a ring surroundmg and spaced from saidxdisks against which the. material is thrown, an outlet conthe circumferential wal of said casing extendin from a point adjacent said ring at one si eofsaid outlet and divergingconstantly therefrom toJthe' other side of said I p l 1 These and other objects and advantages of the invention will be fully set forth in the following description made in-connectioni with the accompanying drawings, in whichlike reference characters refer; to similar duit leading tangentiall from said casing,

Refer-ring to lthe drawings, a machine is shown comprising-{Leasing 10 and while this casing may bevariously made, in theembod-*" -.imentofl. thei -invention illustrated itis shown as comprising a pairiof substantially vertically. disposedJ-flat plates 10a having their lower sldes rectangular and having 1 their bottom edge portions bent outwardly substantially at a right angle to form attache ing flanges 10b; Thesidemembers 10al"are connected by the circumferential wall 100 also illustrated asf;madefrom sheet material having flanges 10d at the sides thereof directed outwardly'and bolted to the "mem-P bers 10a by the circumferentially spaced headed andnuttedbolts 12. The platelOe' :is continued some distance from the edge lOe of the plateslOa atthe top w and reversely bent vto extend parallel withsaid top portion at the lower portion of edge 10a. A short conduit of rectangular-shape having a flange 11a at its outer end extend- .ing at right angles to the sides'thereof is fed over the tpro ecting portionsof plate 100 and --.connected' thereto by the. rivets 11b. The sides ofconduitll abutthe edges 10ep1atesf10a; "A conduit 13 of: ashape sim1lar toconduit1-1 is positioned inalinement therewith andhas a flange 13awhich ge 11a :by thelspaoed headed and nutted b0 casin Brackets 15' aving downwardly it fi ig and horizontally extending 1 arms s 14," conduits 11 d :13 forming tea :discha'r e5, conduit ,for aid are bolted to each plate 10a, said arms carry- .ing bearings a spaced from the plates'10a,

and also held by a set'screw 23. Said hub member has a circumferential flange and a disk 24 has a central opening embracing hub 22 and bolted to said flange by the circumferentially s aced headed and nutted bolts 25. The dis 24 has ribs24a thereon at both sides thereof, which ribs are separated at their inner ends and -diverge outwardly therefrom to the edge of the ends of said ribs being disposed some distance from the opening through said disk. vAnnular plates 26 are .disposed at either side of the disk 24, which overlie and cover the ribs 24a, said disk being of vthe same diameter, of the disk'y24 and having the edge of the opening therethrough disposed at the inner ends of the ribs 24a. The disks 26 have bolted thereto by the circumferentially spaced headed andnutted bolts '28, the frusto-c'onical members 29 which have their smaller ends extending outwardl ,to a point in close proximity'to theside pllates 10a. The-side plates 100 have openings therein about the shaft 16 and plates 30 are secured to the outer side of plates l0a'by the wing nuts 30a. -The-plates 30 extend substantially to the axis of shaft 16, havin recesses in which said shaft is dispose Other plates 31 are secured to said plates 10a:above shaft 16, having their lower edges ofl'set as shown in Fig. 2 to overlap the upper edges of plates 30. The plates 31 carry hoppers 32 and have openings there-- throu h 1n alinement with the hoppers where fy material can pass to the inner sides 0 said plates 10a, said openings being adapted to be closed more 'or less by the slides 33 adjustably held in relation to the plate 30 bya wing nut 34 engaging a bolt 35 which extends through a slot 33a in the late 33. The upper edge of plate 33 is nt outwardly to form a handle means. Shafts 36 are journaled. in, the lower ortions ofplates 30, the same extendingthrough theopenings in disk 26 and being bent substantially at a right an le to have their; ends disposed. closely a jacentthe inner ends of ribs 24a, the terminal ends be ing also bent at a riiht'anthe ends of saidri s eshafts 36 have secured to their outer ends the weight arms 37 which holdsaid shaftsin osition by gravity. A ring 38 surrounds d1sks24 and isk, the. inner' le to extend along.

36, being s aced a short distance outwardly thereof an having a width to extend a short distance beyond the outer edges of said disks and ring 38. Bolts 39 extend through the plate 100 and are threaded at their inner ends into the rin 38 for holding said ring in position, said olts being surrounded by sleeves 40 disposed between plate 100 and said ring. I

In operation, the-oats to be hulled or the other material to be treated, is placed in the hoppers 32. The pulley 19 w1ll be driven at high 'speedby a suitable belt, from a motor, so that disks 24' and 36 are revolved at high speed. Plates 33 willbe adjusted to give the desired feed of material and the material will pass through the side plates 1011' and into the members-29t by which it, will be guided into the space between disk.

24 and the disks 1 26 and-between the ribs 24a. The material is'evenly distributed be tween the disks 24andqowing to the rotaat the lower side of the discharge conduit 11 is quite close toring 38 but diverges from said ring asit passes thereabout and is at its reatest .distance from it at'the top of con uit.11. It has been found in practice that this'structure gives a greatl improved action in the machine, increases t e capacity thereof and. results in a uniform action against the ring 38 so thatthe wear on said ring is uniform throughout the circumference thereof. The machine as stated, has

also been found ,to .be very efficient for cracking corn or other grain and comminuting stock food such as alfalfa. It is quite important that the spaces between the inner en s of ribs 240 be'kept clear. If material lodges between these. ends and the opening is closed u the machine becomes unbalanced and t ehigh 5 eed ofrotation causes the'disks to roar. o kee the inner ends of the. disk clear, themem rs 36 are provided. If any material or foreign. object should stick at the ends of the ribs, it will be struck by members 36 and dislodge. It

I will be noted that the members 36 can swing upwardly and will be returned. to normal positioni'by the weight arms 37.
